I wonder how the searchlight works

How the searchlight works.

At present, high-power aerial searchlights in the domestic and foreign markets generally use xenon lamps.

For the light source, that is, the bulb (or tube) is a high-pressure spherical short-arc xenon bulb. The following will talk about the working principle and maintenance points of high-power aerial searchlights with xenon lamps as the light source.

How it works. The optoelectronic system of the aerial searchlight is divided into a power supply, a high-voltage generator (commonly known as a trigger.

and lamp tube three parts. The working process is simply that when the rated AC voltage is input to the power supply, the power supply will output a stable DC voltage, and then the trigger will work, generating an instantaneous extremely high voltage of about 30 thousand volts, breaking down the xenon in the bulb, and the electrode in series with the flip-flop emits electrons to the other electrode to produce arc light, the flip-flop stops working after the bulb is lit, and the working state of the lamp is low voltage and high current. Special attention should be paid to the fact that the trigger mode of the searchlight is divided into two ways: negative trigger and positive trigger, the negative trigger is characterized by the trigger and the negative pole of the lamp in series, and the negative pole of the lamp emits electrons to the positive pole when working, and the negative circuit (referring to the circuit between the negative pole of the power output and the negative pole of the lamp) is required to strengthen the insulation. The positive circuit is required to strengthen the insulation.

Your question is a bit too general, can you narrow down the question you asked?

Searchlight is a kind of device, with a powerful light source and a concave mirror that can concentrate on projecting the curved light in a specific direction, the role is to illuminate and search at a distance, with the help of the mirror in a small three-dimensional angle to obtain a larger light intensity, suitable for buildings, squares, restaurants, Jingshan, park landmark buildings and gymnasiums, the product can be customized with different colors. Considering the size, weight and ease of operation of the device, most of the searchlights are attached to tripods or movable vehicles, and large searchlights even have special trucks as vehicles.

Searchlight Brands:

1. Philips was founded in 1891 as a Dutch brand, Philips mainly produces household appliances, lighting, medical traveler treatment systems and other products. With 80,000 brand patents, Philips is a powerful brand. Entered the domestic sales market and quickly became a large brand in the domestic electronics industry.

2. Guangdong Jiuliang is a brand established in Guangzhou City, located in Guangzhou High-tech Industrial Development Zone. Guangdong Jiuliang focuses on the application of optoelectronic technology, as well as development, production, manufacturing and self-pride, etc., and is a leading brand in the searchlight market. It has successively passed the domestic quality system certification and has become an innovative and powerful brand in the industry.

Guangdong Jiuliang integrates superior resources, innovative and strong brands, and the products are adhering to excellent quality and are well received by consumers.

3. Dingdian is a brand of Zhongshan Sanyou Electronic Lighting, founded in 2004, and its business scope includes fishing lights, bicycle (bicycle) lights, sports headlights, strong flashlights, bar advertising lights, patrol search lights, super laser cannons, strong light hunting lights, digital searchlights and other mobile lighting products. It has a number of mobile lighting brands such as Sanyou and Vertex, and its Sanyou brand is a partner of ** TV station and Sihai Fishing Channel.

A searchlight refers to a device that produces a directional light source. It reflects the light produced by the light source in a certain direction.

Structure and function.

A searchlight consists of a light source and a reflector, and its anterior segment usually contains one or more optical lenses. Light is gathered into a beam through a reflector (curved or spherical), which is then controlled by the position and combination of the optical lenses, and finally projected.

Searchlights are mainly used in the lighting of vehicles, film shoots, theaters, buildings or exhibitions.

It has a powerful light source, a concave mirror that can concentrate light in a specific direction.

With the help of a reflector or transmissive mirror, the beam is concentrated in a small area.

The military use of searchlights is first of all night air defense (guiding targets for ground anti-aircraft artillery), and in this regard, our army has imitated the Soviet army and specially established an independent branch of the army - searchlight troops. By May 1957, our army had successively established 6 searchlight regiments and 3 independent searchlight battalions. In 1956, the searchlight unit also participated in the Tiananmen National Day military parade.

The second is for the defense of positions and bases (using the cross-"firepower" composed of multiple searchlights to detect and discover abnormalities in the surrounding area in time). The third is ship-born, airborne, or vehicle-mounted searchlights, which are generally used for illumination in low-light conditions. Sometimes it also has a defensive function.

Military searchlights and ordinary civilian searchlights have the following characteristics: (1) brighter and farther irradiation distance; (2) Stronger fog penetration; (3) The technology is more complex and the process requirements are higher; (4) The cost is higher.

Air defense is used to guide the target against the air, positional defense or base defense is used to detect anomalies, the navy also uses searchlights, which are used for night patrols, and searchlights are also used on tanks and aircraft, and the general purpose is lighting. The searchlights of the army are much more complex than those of civilian use, and some of them are almost 2 meters in diameter, and the technical content and cost are very high!

The lamp body is made of stainless steel metal shell. Waterproof, good heat dissipation performance The most advanced metal halide light source is selected, and the reflector of the parallel light parabola is made of pure aluminum with anodizing treatment, with good light gathering effect, high reflective efficiency and lighting brightness, and the effective irradiation distance can reach 5000 meters. It can resist direct fire from high-pressure water cannons and fierce waves.

For large-area and long-distance lighting at night.

It can use a mirror or lens to concentrate the outgoing beam in a small solid angle (usually less than 2 degrees of tools) to obtain a large light intensity.
